Hybrid lead halide perovskite thin films and solar cells by chemical vapour deposition
Ngqoloda, Siphelo (University of the Western Cape, 2021)The organic-inorganic hybrid perovskites such as methyl ammonium lead iodide (MAPbI3) or mixed halide MAPbI3-xClx (x is usually very small) have emerged as an interesting class of semiconductor materials for their application ... -
Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
Ngqoloda, Siphelo (University of the Western Cape, 2015)One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
